well, I'll be a Maverick and suggest something nobody can get any more...
*grins ...the Electro-Voice DS-35, or its slightly more modern version, the EV PL-95

Davie and I bought a set of EV DS-35s in about 1977, after we played on a stage where
the sound men used these. We loved the sound we got from them (and the sound men
and their equipment) that day, and were happy with the mics after we bought them.
We put away our Shure mics for spares. (we'd been using SM 58s). I bought the above pair
of PL-95s a few years later, they seem interchangeable on our stage. Been using them
ever since.
I'll also admit that the Shure SM 58, or it's Beta version, have been industry standard since the days
when every band had to have at least one of these:

That's a long career for the SM-58, ...the vocal master is way obsolete, but the SM 58 is still
in professional use, and most musicians and most sound guys are familiar with how to use
them properly. Including me, and my colleagues. Nothing wrong with the SM-58. Any bugs they
ever had have been worked out long ago.
The reason I'm bringing up the Electro Voice mics is that ours have given great service for decades.
I mean forty years plus, and we've always used them when we needed to set up our own
P.A. Or if we play a venue where they have sound but some diddly mics. We can plug ours
in and sound better. That's the quick review.
For those of you who don't mind a longer essay, here's a picture of the young Kernel and
a young Libby and Davie, playing at Doubie's bar in Flint Mi, circa 1978, using
the EV mics for all three vocals and Davie's guitar. Two of those are in the photo above,
which I just took with my durn phone out on my porch in Tucson.

It isn't that we're so deaf that we'd just buy a set of mics and never question
them, or never try others to see if anything is better. We've been playing many places
in all the years since, and have mostly used what the venues set up for us. So
we're familiar with many different rigs. And we never heard anything that was a
dramatic improvement over what we chose way back then.

these are the same two mics, very new. If you look close at the first pic,
you'll see that the gray paint is all worn off the shafts of the mics, but the heads
are still undamaged and functional. They still sound great, clear, easy to use
without thinking about them, directional, no obnoxious levels of feedback except
under extreme pressure. Fine for my fractured baritone, and for Libby's smokey alto.
Hard to beat IMHO...
Here we are in 2017, same trio, using the same mics, playing an outdoor park concert.
Acapella songs are a good test for any microphone.
